.SH "DESCRIPTION"
.PP
\fBlwres_herror()\fR
prints the string
\fIs\fR
on
\fBstderr\fR
followed by the string generated by
\fBlwres_hstrerror()\fR
for the error code stored in the global variable
\fBlwres_h_errno\fR\&.
.PP
\fBlwres_hstrerror()\fR
returns an appropriate string for the error code gievn by
\fIerr\fR\&. The values of the error codes and messages are as follows:
.PP
\fBNETDB_SUCCESS\fR
.RS 4
Resolver Error 0 (no error)
.RE
.PP
\fBHOST_NOT_FOUND\fR
.RS 4
Unknown host
.RE

.RS 4
No address associated with name
.RE
.SH "RETURN VALUES"
.PP

Unknown resolver error
is returned by

when the value of
\fBlwres_h_errno\fR
is not a valid error code\&.
